1 Claim.

My invention consists of an improvement in Woodworking machines and is adivision of my prior application Ser. No. 10,827. The particular portionof the application herein involved relates to adjustable guiding devicesand mountings therefor, operable on the upper surface of a table, tocontrol the feed or adjustment of articles being treated.

The guide members are so constructed and mounted as to be readilyadjusted to the work in view, and to be readily thrown into operativerelation to the table top and any particular appropriate tool or to beremoved temporarily, While remaining as an accompanying attach ment tothe entire machine.

Certain preferred forms of the invention are shown in the accompanyingdrawings, in which:--

Fig. l is a general plan view of the top of a woodworking machineprovided with two forms of guide;

Fig. 2 is a transverse section on the line IIII of Fig. 1;

Fig. 3 is a transverse section on the line III-III of Fig. 2;

Fig. 4 is a transverse section on the line IV-IV of Fig. 1.

The top 4 of the machine is provided with a series of appropriatesuitably located clearance openings a for extension therethrough ofoperating tools, preferably vertically adjustable or removable, as shownin my prior application. Such tools may be of the class of circular,band or jig saws, rotary planers or sanders, millers or groovers, or ofany type of tool adapted to be adjusted and operated in working relationto the surface of top 4.

I show in Figs. 1 and 4 a guide member 90 having a vertical face capableof adjustment towards or from the clearance slot a of a circular saw 2!for proper spacing and width of cut, and also of parallel adjustmenttherewith. The guide plate 9t, which may be of conventionalconstruction, is connected by a pivoting bolt 9! with terminal 92 of atransverse shaft or spindle 93. Spindle 93 is mounted for slidingengagement through a block 9i provided with a securing screw or bolt 95.

Block St is slidably mounted on a shaft 96 50 carried along andoutwardly from the side of the machine and carried in bearings it. Thelower portion of the block is bifurcated below the shaft hole and isprovided with one or more tightening and loosening bolts or screws 91,by which it may be fixedly held or loosened for outward Divided and thisapplication April 17,

swinging and lowering when not in use, as indicated in dotted lines,Fig. 4.

By longitudinal movement and adjustment of shaft 93 the guide 90 may beaccurately adjusted at any desired distance from the cutting zone of thesaw or other tool, depending on the work.

By the pivoting bolt connection 9| the face of guide 9i] may also belaterally adjusted, as at right angles to the position shown, thusproviding an abutting or limiting contact face for the work at any otherdesired location, by shifting the block 96 along shaft 96 and securingit by bolts ill.

Thus in slotting or cross cutting the piece may be moved towards thetool and against the face of guide 96 thus limiting the movement of thepiece as desired.

I show in Fig. 2 a similar construction and mounting in which thespindle 93 is provided at its inner terminal with a guide plate 98capable of being set at an angle to the table top. For such purpose theguide is provided with rear bearings pivotally connected with the end ofthe spindle by a securing screw or bolt 99 so as to adjust it to anydesired degree of inclination.

By such means the plate may be set to any desired angle to form a slidebearing for a blank A so as to effect a bevel edge planing cut bypassing it over a suitable tool, as a planer l8.

Guide til is thus capable of a considerable degree of adjustment, bothas to angle as well as longitudinally and laterally of the machine, bymanipulation of block 9 3. It may likewise be utilized where possible inconnection with one or more of any of the various cutting tool unitswith which the machine may be equipped, operable through the variousclearance openings at in its top.

The manufacture and application of the adjustable guide of either form,or of any equivalent therefor, to a wood working or other applicablemachine, is comparatively simple, cheap, and is capable of location andof placement when in disuse, in a limited space.

What I claim is:-

In combination with a supporting frame having a work supporting top andan outer laterally mounted cylindrical rod co-extensive with the lengthof the working area of the top and spaced outwardly therebelow, asliding and tip ping bearing block having at its lower portion acylindrical bore for hinging and sliding mounting on said rod andprovided with bifurcated terminals beyond the bore, a tightening andloosening clamping bolt extending through said guiding terminal beingpivotally connected to the end of the guide rod and having tighteningmeans holding the face of the work-guiding terminal in an adjustedangular relation to the horizontal face of the work supporting top, saidbearing block being adapted for location of the guide rod and itsterminal in operative position over the work supporting top and to bethrown outwardly and downwardly with the guide rod in receded positionupon loosening the clamping 10 bolts.
